摘　　要：北部湾某油田调整井A12H在水平段钻遇水层,为防止油井过早出水,在南海西部首次尝试一趟防砂管柱带2个遇水遇油膨胀封隔器进行完井。通过控制井眼轨迹、调整泥浆性能、优化防砂管柱、摩阻计算、采用具有储层保护效果的钻完井液体系等措施为管柱顺利到位、工艺成功实施提供保障。应用结果表明:该完井工艺不仅缩短了完井时间,而且防砂堵水效果好,能延长油井寿命,降低油田开发成本,提高油气采收率,对海上类似作业具有很好的借鉴作用。The water layer were drilled during the horizontal section in A12H well,which may re-sulted in water breakthrough in oil well,so the sand-prevention string with two Oil\water-swell-ing is used in completion.The methods of controlling wellbore trajectory,mud properties adjust-ment,sand-prevention string optimization,friction calculation,choosing reservoir protection drill-ing fluid is used to assure the string running in place.The application results show the completion process can reduce the completion time,the effect of sand-prevention and water shut-off is good.It can extend the life of the well,reduce the cost of field development,and improve oil recovery.The practice can provide experience for the similar operation.
